Abstract
Description
[Technical field]
[0002] The present application relates to the technical field of construction engineering, and in particular to a novel cross-shaped inner partition node of a circular steel tube concrete column. [Background technology]
[0004] Steel has the advantages of high strength and good toughness, but it is prone to instability and damage when under pressure and has a high cost. Concrete has the advantages of high compressive strength and low cost, but its tensile and bending strengths are poor. Steel tube concrete columns combine steel and concrete to form a new type of composite structure, which not only takes advantage of the strength of steel, but also overcomes the disadvantage of steel tube structures being prone to buckling.
[0005] There are two types of existing steel tube concrete column and steel beam rigid connection nodes, one is the external reinforcement link node and the other is the internal reinforcement link node. Figure 1 and Figure 2 As shown in the figure, the outer diaphragm 3 with the external reinforcement ring point will protrude from the outer wall of the steel pipe column, which will have a certain impact on the building facade effect. When the drainage riser is laid close to the edge of the column, it will also conflict with the external reinforcement ring. In order to avoid the problem of the outer diaphragm 3 protruding from the column, the engineering personnel adopted the following method: Figure 2 The inner reinforcing ring node shown is a reinforcing partition 5 arranged inside the steel tube, and a casting hole with a diameter of not less than 200 mm is reserved on the reinforcing partition 5. However, according to previous engineering practices, the biggest disadvantage of using the inner reinforcing ring node is that when pouring concrete, due to the influence of the reinforcing partition 5 in the steel tube concrete column, the concrete cannot be poured compactly, especially at the bottom of the inner reinforcing ring, the concrete is difficult to be dense, holes are formed, and concrete defects are caused, which seriously affects the construction quality and structural safety.

[0031] Please refer to Figures 1 to 6 As shown, this embodiment proposes a novel cross-shaped inner partition node of a circular steel tube concrete column, including a column body 1, an inner partition 2 and a connecting vertical plate 4.
[0032] The column 1 is provided with a first grouting channel 12 , and the inner partition 2 is covered on the first grouting channel 12 to divide the first grouting channel 12 into multiple channels. The inner partition 2 is provided with a grouting circular hole 21 , and the grouting circular hole 21 is a second grouting channel 211 .
[0033] In this embodiment, a first grouting channel 12 is provided on the column body 1, and an inner partition 2 is provided on the first grouting channel 12 to divide the first grouting channel 12 into multiple parts, and a grouting circular hole 21 is provided on the inner partition 2, and the grouting circular hole 21 is used as a second grouting channel 211, so that the poured slurry can be poured into all positions in the steel tube concrete column, which can ensure that the concrete in the core area of the beam-column node is densely poured, so that the node stiffness is greater, the node bearing capacity can be better guaranteed, and it is in line with the prefabricated design concept.
[0034] As a preferred solution but not a specific limitation, a partition groove 11 is provided on the column 1 , and the partition groove 11 is welded and connected to the inner partition 2 to form a whole, so as to form a plurality of first grouting channels 12 .
[0035] In this embodiment, a partition groove 11 is provided on the column 1, and the inner partition 2 is snapped into the partition groove 11, so that multiple first grouting channels 12 can be formed more stably and reliably. Through the cooperation between the partition groove 11 and the inner partition 2, the first grouting channels 12 can be better positioned and fixed, so as to facilitate the operator to pour concrete.
[0036] As a preferred solution rather than a specific limitation, taking into account the construction error, the width of the partition groove 11 is 10 mm larger than the width of the crossbeam of the inner partition 2, and the two are connected by plug welding.
[0037] This embodiment welds the partition groove 11 to the cross beam of the inner partition 2, so that the inner partition 2 and the column 1 form a whole with a tight connection, which can better ensure that during and after the pouring of concrete, the concrete can stably and reliably stay in the new cross-shaped inner partition node of the circular steel tube concrete column to reduce the possibility of concrete overflow.
[0038] As a preferred solution but not a specific limitation, four partition grooves 11 are provided on each circular cross section of the column 1 , and the four partition grooves 11 are arranged opposite to each other in pairs.
[0039] In this embodiment, four partition grooves 11 are provided on each circular cross-section of the column 1, and the partition grooves 11 are arranged opposite to each other in pairs and just opposite to the inner partition 2, so that the inner partition 2 can be better installed on the column 1, so as to ensure the stability and reliability of the new cross-shaped inner partition node of the circular steel tube concrete column, thereby reducing the possibility of concrete overflow.
[0040] As a preferred solution but not a specific limitation, the inner partition 2 is cross-shaped, and the inner partition 2 is provided with a plurality of arc-shaped transition portions 22 , and the first grouting channel 12 is formed between the arc-shaped transition portions 22 and the inner side surface of the column 1 .
[0041] In this embodiment, a plurality of arc-shaped transition portions 22 are provided on the inner partition plate 2, and the first grouting channel 12 is formed between the arc-shaped transition portion 22 and the column 1, so that the grouting process of the formed grouting channel 3 can be smoother and more stable, and the possibility of concrete overflow can be reduced.
[0042] As a preferred solution but not a specific limitation, connecting vertical plates 4 are welded between the inner partitions 2 , and the connecting vertical plates 4 are used to fix and connect the adjacent inner partitions 2 and the columns 1 .
[0043] There are two inner partitions 2 in this embodiment, which are respectively arranged on the two circular cross-sections of the column 1. A connecting vertical plate 4 is provided between the two inner partitions 2. The connecting vertical plate 4 is welded to the two inner partitions 2 and the column 1 so that the two inner partitions 2 and the column 1 can be fixedly connected together, which makes the process of pouring cement slurry smoother and more reliable.
[0044] As a preferred solution but not a specific limitation, the height of the connecting vertical plate 4 is equal to the distance between the partition grooves 11 arranged on the sides of the two opposite sides of the column 1.
[0045] In this embodiment, the height of the connecting vertical plate 4 is arranged at a uniform direction on the side of the column 1 and at different circular cross-sections. Through such an arrangement, the connecting vertical plate 4 can better weld the adjacent inner partitions 2 and the column 1 together, so that the new cross-shaped inner partition nodes of the circular steel tube concrete column after welding are tightly fitted to reduce the possibility of concrete overflow.
[0046] As a preferred solution but not a specific limitation, the minimum distance between the grouting circular hole 21 and the arc-shaped transition portion 22 is one quarter of the diameter of the first grouting channel 12 .
[0047] In this embodiment, the minimum distance between the grouting circular hole 21 and the arc-shaped transition portion 22 is set to one quarter of the diameter of the grouting channel 12, thereby ensuring the stability and reliability of the structure.
[0048] As a preferred solution but not a specific limitation, the maximum diameter of the grouting circular hole 21 is less than or equal to the width of the crossbeam of the inner partition 2 .
[0049] The maximum diameter of the grouting circular hole 21 of the present embodiment is less than or equal to the width of the cross beam of the inner partition 2. Once it is larger than the width of the cross beam of the inner partition 2, the inner partition 2 will break. The maximum grouting circular hole 21 is equal to the width of the cross beam of the inner partition 2, that is, the edge of the cross beam is tangent to the grouting circular hole 21, which can effectively avoid the problem of the inner partition 2 breaking due to the grouting circular hole 21 being too large, so that the new cross-shaped inner partition node of the circular steel tube concrete column is more stable.
[0050] As a preferred solution but not a specific limitation, the optimal diameter of the grouting circular hole 21 is half of the width of the beam and must not be less than the minimum diameter.
[0051] As a preferred solution but not a specific limitation, the minimum diameter of the grouting circular hole 21 is 150 mm.
[0052] In this embodiment, the minimum diameter of the grouting circular hole 21 is set to 150 mm. If the diameter of the circular hole is smaller than this value, the grouting pump truck will not be able to accurately insert the pump pipe into the circular hole for grouting, which will cause cement slurry to overflow and waste construction materials. When the hole diameter is too small, the oscillator cannot penetrate deep into the grouting hole to vibrate the cement tightly, which will cause the poured concrete structure to be suspended or loose. Therefore, this setting can better meet the needs of construction.
[0053] As a preferred solution but not a specific limitation, the minimum diameter of the first grouting channel 12 is 150 mm, and the minimum diameter of the column 1 is 900 mm.
[0054] In this embodiment, the minimum diameter of the first grouting channel 12 is set to 150 mm. If the first grouting channel 12 is smaller than this value, the grouting pump truck will not be able to accurately insert the pump pipe into the circular hole for grouting, which will cause cement slurry to overflow and waste construction materials. When the hole diameter is too small, the oscillator cannot penetrate deep into the grouting hole to vibrate the cement tightly, which will cause the poured concrete structure to be suspended or loose. Therefore, this setting can better meet the needs of construction.
[0055] In this embodiment, an inner partition 2 is provided on the two circular cross sections of the column 1. The inner partition 2 is formed by welding two mutually perpendicular beams. A corresponding first grouting channel 12 is formed between the intersection of the two beams and the side surface of the column 1. Four corresponding first grouting channels 12 can be formed. In addition, the grouting circular hole 21 is converted into a second grouting channel 211. The new cross-shaped inner partition node of the circular steel tube concrete column of this scheme has 5 grouting channels 3.
[0056] In this embodiment, a first grouting channel is provided on the column body, and the inner partition cover is provided on the first grouting channel, thereby dividing the first grouting channel into multiple ones, and then a grouting circular hole is provided on the inner partition, and the grouting circular hole is used as a second grouting channel, so that the poured mud can be poured into all positions in the steel tube concrete column, which can ensure that the concrete in the core area of the beam-column node is poured densely, so that the node stiffness is greater, and the node bearing capacity can be better guaranteed, which is in line with the prefabricated design concept.
